f rlhis invention relatesto oil savers particularly adapted foruse in `connection with oil wells.. l i i.,

Heretofore, it has been customaryto provide an. oil saver which comprisedafhousing adaptedto be threaded on the uppersection of :Well casing.V This housingI surrounded and packing wasearrangedV in fthe housing around the cablewhereby oil could not escape. Inthis type of oil saver the'hoising `had. to be disengaged roni thel well casing in:V order to remove thetoolsV from the hole andsthe saver often Ywas 4quickly worn out' bythe acl' tion of the cable Vgradually y cutting away; p0r-V tions V.oi' the housing.

; objectof thisinvention .is tov Voil saver whereinthe housing is` provided witha removablelinerwhereby the tools `may be quicklyrun intoorl out ofthe-hole without disengagingtheihousing fromfthegwell cas;v

m H ,i I g thnother Objectis toprovide a 'devioeof the type referred to wherein. the-lineris provided with pockets in which .suitable` acking .is ar ranged, thelayers of packing being angularly arranged with respect to each other. 'A further object is to provide a device-of the-type referred towherein-the housing is provided .with .suitable openings adaptedI .to

align with the `pockets inthe liner, means be.-

ing carried bythe housing to force the pack ing into engagement withthewell cable. l

A further Objectis to provide adevice of the. type i referred .to wherein theVV housing? is provided: with a plurality ofA openings adapt-` ed to `:receive Vpacking. followersywhereby the packing may:beforced into engagement withY the cable, the Afollowers: being movable toa position within thehousing which permit removal ofthe liner.

A1 further i obj ect'. is to f :jgirovide'J Asuitable cover'platesfor the .openingsl in the housing,

the! plates being provided with :'lthreaded u openings through which the stem ofthepackj Figure lisa rontielevation, Y

may be actuated Jfromswithout the housing.

. Aurtherobject is to provide-means for" reducing friction to a minimum as the tools arerun into and out of the hole,said :meansv alsofserving to guidethe cable in its ascent g kand descent.

23 is adapted to be threaded on to the uppermost section of well casing and the section 21 fits within this sleeve. A plurality of bolts 24 extend through the upper portion of theV sleeve 23 and project above the. annular flange 22 whereby the housing may be connected to the well casing 24. Adjacent its upper extremity the housing is providedwith an enlarged portion 25 a portion of which is internally threaded as shown at 26. Intermediateits ends the housingV is provided internally with an annular tapered seat 27 for a purpose to be described. Y

Referring to Figuresv 2, 3 and4 the nuineral 28 designates a linerasy a whole formed( withu a llongitudinal bore .29' 'through which a cable 30 or the like is adapted-to extend... The liner 28 is preferably formed of a pair of complementary sections .31.fand.' 32 securedsemi#annular.` tapered portion41r'and directly,

beneath the tapered portionsgreduced 'semiannular :transverse portions 42 and 43Jare` provided, connected by webs yor ribsl 44 whereby a pair/of somewhat smaller pocketsI 45 and 46 are provided. The pockets 45 and46 form a continuous opening trans--V verselyof the' liner-"andare vsingularly 'arranged with respetto the pockets 39 and 40-7 -t'his .angle preferably being 909.1.V

' Adjacent lits upper-extremity each. section of the liner is provided with an enlarged semi-annular threaded portion 47- and on 'the top thereof the liner is provided with suitable bearings 48 in which arejournaled rolllers 49adaptedto engage the cable 30.

'Packing-members 50 and 51 are arranged rFhe liner 28 is adapted tocfit within the housing 10 and when in its Vproper position the pockets 39 and 40will be inealinement with the openingsY 12finthe housing. At the same time Vthe pockets 45' .and 46 .will also be in alinement with the openings'13 in the housing. `As shown in rFigure2, packingfollow.- ers.. 52 provided with threaded stems53 are i utilized to force the .packing intoengage-V ment with the cable 30. The stem` 53-is' threaded-'into the opening" 15 in the plate'14 andany suitable. connection maybe made between the follower and'its stem.. Asshown the inner-extremity 'of the stern is reduced as ati 54 andprojects through anopeniiirginethe follower and the end 0f the stem'isups'et and Y 23 and bolts 24, aspreviously described. The .tools arethen suspended onthecable30 by.

means of .therope sockie'tl58`and comlernen#l 80 tary sections of lthe liner'28 `lare' bo ted together above the rope socket." The'liner is then" lowered into the housing and -turned until-the threeded portion 47 firmly `engages the threads 26 in the housing and the pockets inthe liner are in alinernent with .the respective openings inthe housing.YV The followers 52 and 56 can then be utilized to force the packing"V into. engagement. with. the cable 30 and prevent theY leakage of oilalong; the cable. The arrangement of thev .upper and lower packing. angular relation formsan effective seal to prevent the leakage of; oil. The inner ezctren'iitie'sV ofthe packing. members do not quite touch when'forcedfintoengagement .9.5 with thecablegbut leakage through the open.l ings .between thefinner extremities is prevented by reason ofthe: angular 'arrangement re` ferredY to; as rwill .be apparent.
